So-Called Dollars are a category of non-federal propaganda, commemorative, or medallic pieces primarily issued in the United States. They are often minted for events or occasions, lacking official currency status. The Hibler-Kappen catalog is a widely used reference for identifying and valuing these items, particularly focusing on those produced from the 19th century onwards. The 1881 pieces under this classification may reference specific commemorative events or milestones relevant at the time, showcasing a blend of artistry and historical significance in collectible numismatics.
